Abstract
The utility model relates to a slowly close vertical check valve of hammer that disappears, especially one kind produces the slowly close vertical check valve of hammer that disappears that water hammer phenomenon is little. The utility model discloses a valve body, the case, the disk seat, the seal receptacle, it gets into end and medium outflow end to be equipped with the medium on the valve body, the medium gets into the DN value less than or equal to 100 of end, an elastic component has been cup jointed on the seal receptacle, and this elastic component one end contacts with the seal receptacle, the other end contacts with the case, still be equipped with the guide of a plurality of with the case direction on the valve body.
Description
Technical field
This utility model relates to a kind of Slow Close and disappears hammer Vertical Lift Check Valves, and especially a kind of little Slow Close of water hammer that produces disappears hammer Vertical Lift Check Valves.
Background technology
Check-valves is widely used in iron and steel, metallurgy, oil and chemical industry etc., and some have the pump discharge position of relatively strong corrosion industry pipeline. It is mainly used to stop pipeline medium to flow backwards, it is prevented that pump and drive motor reversion thereof and the releasing of container inner medium. Some small-bore and also in deep-etching pipeline, although common steel check-valves can guarantee that in pressure-bearing, but resistant to corrosive media effect can not be played; And check-valves most of actually used in, it is determined for quick closedown qualitatively, and in closure of check ring moment, medium is reverse flow, closedown along with flap, medium is rapidly decreased to zero from maximum refluence speed, and pressure then raises rapidly, namely produces " water hammer " phenomenon being likely to pipe-line system has destruction. So water hammer is a fatal constraint of whole pipe-line system.
Summary of the invention
Problem to be solved in the utility model is to provide a kind of Slow Close and disappears hammer Vertical Lift Check Valves, and especially a kind of little Slow Close of water hammer that produces disappears hammer Vertical Lift Check Valves.
For solving above-mentioned technical problem, including valve body, spool, valve seat, seal receptacle, described valve body is provided with media inlet end and medium outflow end, the DN value of described media inlet end, less than or equal to 100, described seal receptacle is socketed with an elastic component, and described and this elastic component one end contacts with seal receptacle, the other end contacts with spool, and described valve body is additionally provided with several guides led by spool.
After have employed said structure, DN value is less than or equal to 100, be equivalent to have employed a kind of small-bore check-valves, the water hammer that such medium produces after flowing into will obtain bigger alleviation, and arranging of elastic component can effectively control pump when quitting work, when the valve medium sealing when flowing backwards and pipeline medium bigger pressure, spheroid and seal receptacle better elasticity play Slow Close effect, effectively reduce water hammer. The setting of guiding rib, can make the be in a good mood direction of muscle of spherical ball run, and medium can be allowed to pass through.
As further improvement of the utility model, described guide is four guiding ribs being arranged on valve body, and described guiding rib is respectively arranged at the upper and lower both sides of valve body, and described guiding rib is the prominent muscle of arc-shaped.
After have employed said structure, the guiding rib of arc-shaped well can coordinate with ball valve core, serves the technique effect of guiding.
As further improvement of the utility model, described elastic component is the elastic rubber ring being socketed on seal receptacle, and the elastic surface of described elastic rubber ring is towards spool place.
After have employed said structure, elastic rubber ring good springiness, deformation rate is low, forever pressure, effectively controlling pump when quitting work, when the valve medium sealing when flowing backwards and pipeline medium bigger pressure, spheroid and seal receptacle better elasticity play Slow Close effect, effectively reduce water hammer.
Accompanying drawing explanation
Fig. 1 show Slow Close disappear hammer Vertical Lift Check Valves sectional view.
Detailed description of the invention
As it is shown in figure 1, this utility model includes valve body 1, spool 2, valve seat 3, seal receptacle 4, described valve body is provided with media inlet end and medium outflow end, core adopts the PTFE that wearability is good, efficiently solves the deformation of spheroid when medium washes away and causes seal failure. Seal receptacle adopts advanced material FPM fluorubber, this elastic properties of materials is good, deformation rate is low, forever pressure, can effectively control pump when quitting work, when the valve medium sealing when flowing backwards and pipeline medium bigger pressure, spheroid and seal receptacle better elasticity play Slow Close effect, effectively reduce water hammer. The DN value of described media inlet end, less than or equal to 100, described seal receptacle 4 is socketed with an elastic component, and described and this elastic component one end contacts with seal receptacle, and the other end contacts with spool, and described valve body is additionally provided with several guides led by spool. DN value is less than or equal to 100, be equivalent to have employed a kind of small-bore check-valves, the water hammer that such medium produces after flowing into will obtain bigger alleviation, and arranging of elastic component can effectively control pump when quitting work, when the valve medium sealing when flowing backwards and pipeline medium bigger pressure, spheroid and seal receptacle better elasticity play Slow Close effect, effectively reduce water hammer. The setting of guiding rib 5, can make the be in a good mood direction of muscle of spherical ball run, and medium can be allowed to pass through. Described guide is four guiding ribs being arranged on valve body, and described guiding rib 5 is respectively arranged at the upper and lower both sides of valve body, and described guiding rib is the prominent muscle of arc-shaped. The guiding rib 5 of arc-shaped well can coordinate with ball valve core, serves the technique effect of guiding. Described elastic component is the elastic rubber ring being socketed on seal receptacle, and the elastic surface of described elastic rubber ring 6 is towards spool place. Elastic rubber ring 6 good springiness, deformation rate is low, forever pressure, can effectively control pump when quitting work, when the valve medium sealing when flowing backwards and pipeline medium bigger pressure, spheroid and seal receptacle better elasticity play Slow Close effect, effectively reduce water hammer.
